Abstract: ISOTHERMAL GROWTH OF BUBBLE DOMAIN GARNET FILMS            Abstract of the Disclosure A technique for reproducibly and uniformly growing magnetic bubble domain garnet films under isothermal conditions.  In one situation, a fluxed melt is prepared such that the primary phase (first phase to crystallize) is orthoferrite rather than garnet.  At the growth tempera-ture and prior to substrate-melt contact, the melt is saturated with respect to orthoferrite and supersaturated with respect to garnet.  Dur-ing growth, the orthoferrite crystals are separated from the supersaturated garnet solution so that a high quality garnet film is grown on the sub-strate.  After growth, the melt is reheated to above its liquidus (crystal-lization) temperature to dissolve the orthoferrite crystals, thus pro-viding a nutrient source for garnet constituents which can be used dur-ing subsequent expitaxial depositions.

Abstract: METHOD OF REMOVING FINELY DIVIDED          SOLIDS FROM GAS        ABSTRACT OF THE INVENTION    Finely divided solids are removed from a feed gas by passing the gas through an elongated annular mass of solid particle form contact material held between two generally concentric cylindrical walls.  The outer wall is louvered having vanes outwardly inclined to the vertical at 15 to 80 degrees and the louver openings are of such width that most of the particles of con-tact material are capable of passing through them.          The inner wall is perforated to permit passage of gas through the wall and may be louvered similarly to the outer wall but having the louver vanes inwardly inclined.  The finely divided solids are entrained or trapped in the mass of contact material which is moved downwardly through and out of the annular space between the two con-centric cylindrical walls.  The contact material is then treated to separate entrained finely divided solids and returned to the upper end of the annular space.  Movement of the contact material through the annular space causes a small portion of it to pass through the louvers of the outer cylindrical wall preventing plugging of the louvers which would otherwise be caused by accu-mulation of the finely divided solids contained in the feed gas.  Gas having reduced solids content is withdrawn from the space enclosed by the interior cylindrical wall.  Apparatus for making the separation is described.

Abstract: ABSTRACT  OF  THE  DISCLOSURE The present invention relates to novel .beta.-lactam containing compounds and to their preparation, and the applicant has previously disclosed that compounds of the formulae (I) and (II):                           (I)                  (II) and their salts and esters are .beta.-lactamase inhibitors.  A further group of compounds which have intrinsic .beta.-lactamase inhibitory properties has now been discovered and the new compounds are also useful intermediates in the prepara-tion of the compound of the formula (II) and its salts and esters.  Hence the present invention provides compounds of the formula (III):       (III) wherein R1 is an acyl group and salts and esters thereof.   The group R1 in the above formula may represent a wide variety of acyl groups of the formula R2CO which may contain up to 16 carbon atoms, although in general, it more suitably contains up to 12 carbon atoms and is an acyl group found in the acylamino side chain of the known antibacterially active penicillins and cephalosporins. The present invention also provides a process for the preparation of compounds of the formula (III) as hereinbefore described and salts and esters thereof which process comprises acylation of the corresponding compound of the formula (I) as hereinbefore described or salt or ester thereof with a compound of the formula (V):     R2 - CO2H             (V) or a reactive acylating derivative thereof wherein R2-CO2H is an organic carboxylic acid.

Abstract: ABSTRACT OF THE DISCLOSURE           A space thermostat for controlling the two-stage operation of both heating and cooling apparatus includes two single-pole, double-throw mercury type switches operatively connected to a single bimetallic coil.  One switch energizes stage one of the heating apparatus when tilted in one direction and energizes stage two of the cooling apparatus when tilted in the other direction.  The other switch energizes stage two of the heating apparatus when tilted more in the direction which effected the energizing of stage one of the heating apparatus and energizes stage one of the cooling apparatus when tilted less in the direction which effected the energizing of stage two of the cooling apparatus.  The switches are adjustably mounted with respect to each other so that the differential between stages can be adjusted to be the same as the dif-ferential of each switch.  With the differential between stages so adjusted, the energizing temperature of stage one of the heating appara-tus and the energizing temperature of stage one of the cooling apparatus are automatically the same, a feature which simplifies the calibration of the thermostat.  Printed circuit boards, attached to the switches, contain a portion of the internal wiring so as to reduce the amount of loose wiring.

Abstract: Abstract of the Disclosure Solid carbonaceous fossil fuels such as coal, lignite and peat are treated with an aqueous medium containing a novel catalyst to remove undesirable constituents and pro-duce valuable products.  The catalyst is prepared by steps including admixing a water soluble alkali metal silicate with an aqueous medium containing carefully controlled amounts of dissolved water soluble substances which are sources of calcium ion and magnesium ion, reacting the same to produce an aqueous colloidal suspension of the reaction product, admixing a micelle-forming surfactant with the aqueous medium, and agitating the aqueous medium containing the colloidal particles and surfactant to form catalyst-containing micelles. In one variant, combustible sulfur and nitrogen compounds and alkali metal ash are removed, and the resulting treated fuel may be used in urban areas where strict air pollution regulations must be met.  The coal, lignite and peat react with water and/or the components thereof when treated with an aqueous medium containing the catalyst, and/or are oxidized or otherwise chemically changed to produce valuable organic chemicals which are soluble in one or more solvents including the aqueous treating medium, water soluble and water insoluble organic extraction solvents, aqueous solutions of organic and inorganic acids and aqueous solutions of organic and inorganic bases.  The treated insoluble particles of coal, lignite and peat remaining after extraction with one or more of the above solvents have ion exchange properties and are useful as an absorbent or adsorbent for liquid phase organic and inorganic compounds and for removing organic and inorganic acidic components from gaseous mixtures in a manner similar to activated carbon.  In a further variant, particles of a fossil fuel containing metal values are treated with an aqueous medium in the presence of the catalyst, and thereafter the treated particles are separated from the aqueous medium and extracted with an aqueous leach solution in which the metal values are soluble.  The solubilized metal values are recovered from the resulting leach liquor following prior art hydrometallurgical techniques.  In still a further variant, the solid particles of the treated coal, lignite and peat, or components thereof. are treated and solubilized in the aqueous catalyst suspension to produce a novel aqueous solution which has highly unusual and unexpected properties.  The resultant solution has unique germicidal, medicinal and synergistic properties, and it also has important applications in agriculture and animal husbandry.

Abstract: MASTER LINK ASSEMBLY FOR CRAWLER TRACTOR TRACK ASSEMBLY            ABSTRACT OF THE DISCLOSURE     A master link assembly in a continuous flexible track assembly for a crawler tractor comprises two later-ally spaced apart (left and right) parallel master links and each master link comprises two overlapping half-links held in alignment by a pin extending into registering pin holes in the half-links.  The overlapping half-links are mechanically secured together in fixed relationship by track shoe capscrews which extend through holes in a master link track shoe which overlies both half-links and screw into tapped cap screw holes in the half-links.  Besides aligning the overlapping half-links, each pin also serves as a safety connection in case the capscrews break and also enables removal of the capscrews and replacement of the track shoe without breaking the track assembly.  Axial dis-placement of a pin from its pin holes is prevented by arranging at least one tapped screw hole in each half link so that a capscrew, when fully inserted therein, engages a groove in the side of the pin and prevents axial movement of the pin.

Abstract: ABSTRACT OF THE DISCLOSURE The quality and useful life of regenerative-cycle type incandescent lamps that employ iodine as the halogen are enhanced by dosing the lamps with a carefully controlled amount of SnI4 which decomposes when the lamp filament is energized and provides from about 0.05 to 0.20 micromole of vaporized elemental iodine per ml. of bulb volume within the lamp during operation.  The resulting increase in the amount of iodine that is converted into atomic rather than molecular form within the energized lamp permits elongated iodine-cycle lamps having singly-coiled filaments to be operated in any position in contract to conventional iodine-cycle lamps of the same configuration and construction that exhibit early blackening of the top portion of the envelope when the lamp is operated in a vertical position.  The undesirable light-absorption and color distortion effects characteristic of conventional iodine-dosed lamps are also reduced, thus increasing the lamp efficiency.
